Those are just a few of the names that have been in the headlines of MMA lately and it had nothing to do with winning fights. All three fighters tested positive for a banned substance or elevated levels of testosterone, and it once again raises the question if enough is being done to curb performance enhancing drug use in mixed martial arts.

The UFC recently instituted a new drug policy that screens all incoming fighters who intend to sign a contract with the promotion, and they must test clean before the contract can be tendered. In addition, all competitors on The Ultimate Fighter must also be tested prior to their admission onto the reality show.

Outside of those screening requirements, the UFC does no other testing on their own, except when the promotion operates an event in a location where the local sanctioning body does not provide for drug testing or in global locals where there is no sanctioning body. In areas where there is a sanctioning body, the athletic commissions in each area are responsible for drug testing the athletes as they see fit. Commissions like Nevada have instituted out-of-competition drug screenings to help curb performance enhancing drug use.
